Book Description
"A short, excellent account of [Leavitt’s] extraordinary life and achievements." —Simon Singh, New York Times Book Review George Johnson brings to life Henrietta Swan Leavitt, who found the key to the vastness of the universe—in the form of a “yardstick” suitable for measuring it. Unknown in our day, Leavitt was no more recognized in her own: despite her enormous achievement, she was employed by the Harvard Observatory as a mere number-cruncher, at a wage not dissimilar from that of workers in the nearby textile mills. Miss Leavitt’s Stars uncovers her neglected history.

Book Description
“A short, excellent account of [Leavitt’s] extraordinary life and achievements.”—Simon Singh, New York Times Book Review At the beginning of the twentieth century, scientists argued over the size of the universe: was it, as the astronomer Harlow Shapley argued, the size of the Milky Way, or was there more truth to Edwin Hubble’s claim that our own galaxy is just one among billions? The answer to the controversy—a “yardstick” suitable for measuring the cosmos—was discovered by Henrietta Swan Leavitt, who was employed by the Harvard Observatory as a number cruncher, at a wage not dissimilar from that of workers in the nearby textile mills. Miss Leavitt’s Stars uncovers her neglected history, and brings a fascinating and turbulent period of astronomical history to life.

Book Description
Henrietta Levitt was the first person to discover the scientific importance of a star’s brightness—so why has no one heard of her? Learn all about a female pioneer of astronomy in this picture book biography with audio. Henrietta Swan Leavitt was born on July 4, 1868, and she changed the course of astronomy when she was just twenty-five years old. Henrietta spent years measuring star positions and sizes from photographs taken by the telescope at the Harvard College Observatory, where she worked. After Henrietta observed that certain stars had a fixed pattern to their changes, her discovery made it possible for astronomers to measure greater and greater distances—leading to our present understanding of the vast size of the universe. An astronomer of her time called Henrietta Leavitt “one of the most important women ever to touch astronomy,” and another close associate said she had the “best mind at the Harvard Observatory.” Henrietta Leaveitt's story will inspire young women and aspiring scientists of all kinds and includes additional information about the solar system and astronomy. This eBook edition also includes audio accompaniment.

Book Description
A century ago, a brilliant woman found the key to the vastness of the universe; her name was Henrietta Swan Leavitt. She was hired by Harvard Univ. to calculate the positions and luminosities of stars in astronomical photos. She discovered a new law, one that would transform the field of cosmology. Because of Leavitt¿s discovery, astronomers could use a kind of star known as a ¿variable¿ as a cosmic yardstick. Her law settled an important astronomical question; how big is the universe? Using Leavitt¿s law, the astronomer Edwin Hubble was able to prove that there were galaxies beyond the Milky Way, and that the universe is unfathomably large. ¿A masterly account of how we measure the universe and the moving story of a neglected genius.¿ Illus.

Book Description
From #1 New York Times bestselling author Dava Sobel, the "inspiring" (People), little-known true story of women's landmark contributions to astronomy A New York Times Book Review Notable Book Named one of the best books of the year by NPR, The Economist, Smithsonian, Nature, and NPR's Science Friday Nominated for the PEN/E.O. Wilson Literary Science Writing Award "A joy to read.” —The Wall Street Journal In the mid-nineteenth century, the Harvard College Observatory began employing women as calculators, or “human computers,” to interpret the observations their male counterparts made via telescope each night. At the outset this group included the wives, sisters, and daughters of the resident astronomers, but soon the female corps included graduates of the new women's colleges—Vassar, Wellesley, and Smith. As photography transformed the practice of astronomy, the ladies turned from computation to studying the stars captured nightly on glass photographic plates. The “glass universe” of half a million plates that Harvard amassed over the ensuing decades—through the generous support of Mrs. Anna Palmer Draper, the widow of a pioneer in stellar photography—enabled the women to make extraordinary discoveries that attracted worldwide acclaim. They helped discern what stars were made of, divided the stars into meaningful categories for further research, and found a way to measure distances across space by starlight. Their ranks included Williamina Fleming, a Scottish woman originally hired as a maid who went on to identify ten novae and more than three hundred variable stars; Annie Jump Cannon, who designed a stellar classification system that was adopted by astronomers the world over and is still in use; and Dr. Cecilia Helena Payne, who in 1956 became the first ever woman professor of astronomy at Harvard—and Harvard’s first female department chair. Elegantly written and enriched by excerpts from letters, diaries, and memoirs, The Glass Universe is the hidden history of the women whose contributions to the burgeoning field of astronomy forever changed our understanding of the stars and our place in the universe.

Book Description
THE STORY: When Henrietta Leavitt begins work at the Harvard Observatory in the early 1900s, she isn’t allowed to touch a telescope or express an original idea. Instead, she joins a group of women “computers,” charting the stars for a renowned astronomer who calculates projects in “girl hours” and has no time for the women’s probing theories. As Henrietta, in her free time, attempts to measure the light and distance of stars, she must also take measure of her life on Earth, trying to balance her dedication to science with family obligations and the possibility of love. The true story of 19th-century astronomer Henrietta Leavitt explores a woman’s place in society during a time of immense scientific discoveries, when women’s ideas were dismissed until men claimed credit for them. Social progress, like scientific progress, can be hard to see when one is trapped among earthly complications; Henrietta Leavitt and her female peers believe in both, and their dedication changed the way we understand both the heavens and Earth.

Book Description
It was not always known that the Milky Way is just one of many galaxies in the universe. Edwin Hubble is the man who discovered this startling idea and that the universe was expanding. As a result of these discoveries, Hubble became an international celebrity, and is remembered today as a genius of science.
